p_ungroup {dtrackr}

Remove a stratification from a data set

Description

Un-grouping a data set logically combines the different arms. In the history this joins any stratified branches and acts as a specific type of status(), allowing you to generate some summary statistics about the un-grouped data. See dplyr::ungroup().

Usage

p_ungroup(
  x,
  ...,
  .messages = .defaultMessage(),
  .headline = .defaultHeadline(),
  .tag = NULL
)

Arguments

x

A tbl()

...

Arguments passed on to dplyr::ungroup

.messages

a set of glue specs. The glue code can use any any global variable, or {.count}. the default is "total {.count} items"

.headline

a headline glue spec. The glue code can use {.count} and {.strata}.

.tag

if you want the summary data from this step in the future then give it a name with .tag.

Value

the .data dataframe but ungrouped with the history graph updated showing the ungroup operation as a new stage.
